Title: Improvements in or relating to flux valve magnetic compasses
IPC: G01C17/36
Filed: 1941-12-10
Abstract: 638,971. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Dec. 10, 1941, No. 15940. Convention date, Nov. 20, 1940. [Class 97 (iii)] [Also in Groups XXXVI and XXXVIII] A gyro compass is controlled by a stabilized magnetic compass of the flux-valve type. In one arrangement for aircraft, the flux valve, which may be carried by a pendulum or by the rotor bearing casing of the gyro, is connected to the rotor of a Selsyn receiver, the output of which, after amplification, controls a relay 36 polarized by a coil 37 which is fed by current of the same phase as the compass but doubled in frequency. This relay controls an induction motor structure associated with one of the horizontal trunnions so as to produce a torque for causing the gyro to precess, carrying with it the rotor 28 of the Selsyn, until it is in the magnetic meridian, the Selsyn output then being zero. During turns, the compass is disconnected from the Selsyn by a switch controlled by the rate-of-turn gyro. In another arrangement, in which the compass is part of an automatic pilot system, operation of a handle 53 for changing the course, rotates the compass 41 and the follow-up disc 56, the compass being disconnected by a centrifugal switch 50 while the handle is operated. The craft, in known manner, takes a new course by the operation of a pilot motor until the follow-up disc resumes its previous position in relation to the shaft 30<SP>1</SP> carried by the gyro. Thereafter, the gyro is kept in agreement with the compass by similar means to that previously described except that the Selsyn is omitted, the differential relay being controlled directly by the amplified compass currents. The magnetic compass may be carried by the gyro, in which case the Selsyn 23 is not mechanically coupled to the gyro rotor. Specification 599,428, [Group XXXVI], is referred to.

Sextant-type instruments.-A sextant or like instrument is provided with an adjustable scale enabling a direct reading of the latitude to be taken by providing automatic correction for declination of the observed body, height of eye and dip, solar semi-diameter parallax and refraction. The instrument comprises the usual arm A with vernier B, adjustable over the altitude scale C. Concentric with the scale C and in the same plate is a slot F, part of which is cut completely through the plate, and mounted in this slot is the adjustable latitude scale G provided with a vernier J on the arm A. The graduations of the scale G are not exact degrees but are 0.025 minutes less than degrees, and the vernier J is graduated in both directions. A small plate L can slide in a recess M offset from the slot F and is adjusted by a tangent screw and graduated head in accordance with the height of the observer's eye. The plate L carries four lines, Fig. 4, one indicated by an asterisk and another by a V mark 15.9 minutes, measured on the scale G, to the right of the former line. On each side of the V line are two others, marked S and W, equidistant from it by 0.3 minutes. The asterisk line is used for observations on stars and the others for observations on the sun's lower limb, the V line being used in spring and autumn and the lines S, W in summer and winter respectively. In setting the instrument the plate L is adjusted for height of eye and clamped. The arm A is then moved so that the upper of the three marks K, Fig. 7, coincides with the appropriate line on the plate L. The arm A is then clamped and the scale G is adjusted to the appropriate line, the declination of the body to be observed being set to this line. The arm A is then released and the instrument is used in the ordinary way. The latitude is read off on the scale G.

Abstract: 1514128 Magnetic storage arrangements ROCKWELL INTERNATIONAL CORP 21 April 1976 [18 Sept 1975] 16166/76 Heading H3B In a magnetic bubble store comprising a plurality of storage loops SA-SD, Fig. 1, in a magnetic sheet 100, writing into a single loop selected by a controller 50 is effected by creating appropriate bubble domains at a generator 10, replicating the bubbles at an output replicator 14 having propagation paths 12A-17A ... 12D-17D extending to respective storage loops, and using an input decoder 16 to suppress the bubbles in each propagation path except for the path extending to the input 21 of the selected loop. Similarly for readout the bubbles in each of a plurality of loops are transferred (destructive readout), or replicated (N.D.R.O.), at a switch 20A-20D into respective propagation paths 19A-19D extending to a multiple input detector 24 and detector output 26, all the bubbles in the paths except that extending from a selected loop being annihilated by an output decoder 22. The bubble domains are driven by an in-plane rotating magnetic field HR along propagation paths such as 12, 12A ... 12D, Fig. 2, defined by chevron overlay patterns. This figure shows in detail a bubble output replicator 14 consisting of a series of bubble dividers 30A-30C coupled by units 36, 36A ... each formed of two parallel and elongate chevron stages. In each divider the bubbles are elongated over two chevron stages 32, 33, and are then separated with assistance by a holder bar 31. In the units 36, 36A ... a pusher bar 29 directs each elongate bubble into the next bubble divider. Fig. 3 shows one form of output decoder in which unidirectional current in two out of four control lines A, A, B, B selectively causes annihilation of bubbles in three out of the four propagation paths 12A-12D. Each control line has a unique pattern of narrow and wide portions such as 75, 75A in line A, current in a wide portion 75 having no effect on a bubble in a path which it overlays, while current in a narrow portion 75A concentrates the field produced by the current sufficiently to annihilate a bubble. A modification is shown in Fig. 4, which uses pulses of selected direction over two lines in combination with the positions where the narrow control line portions cross the chevron paths to determine in which paths bubbles are to be suppressed.

A porous frame 15 surrounds the electrode.  The electrode was made by compressing at 200 kg./cm.2 14 gm. carbonyl nickel (particle size less than 5 microns) in an annular mould to form frame 15 and introducing and lightly compressing one of the working layers 2 which comprises 5 gm. of a double skeleton catalyst, e.g. 3 gm. carbonyl nickel powder and 2 gm. Raney alloy (50/50 nickel, aluminium, particle size 35-50 microns. 9 gms. of carbonyl nickel and 4 gms. of potassium chloride crystals (particle size 200-400 microns) forming the coarse pored gas distributing layer 6 is introduced and lightly pressed followed by another 5 gms. of the above mentioned working layer powder.  The three layers were compressed at 680 kg./cm.2 to the height of the frame 15.  The structure so formed was placed in a mould of the same diameter, the bottom of which was lined with a powdered surface layer, and was covered with a powdered surface layer. Each surface layer 1 comprised 2.4 gm. carbonyl nickel and 1.6 gm. of Raney alloy, e.g. 50/50 aluminium-nickel particle size 7.5-9 microns.  The resultant body was compacted at 3000 kg./cm.2 at a temperature of 370  DEG C. and then sintered in an atmosphere of hydrogen for twelve minutes at 820  DEG C.  The inactive components of the Raney alloy and the potassium chloride of the gas distributing layer were leached out.  Wires of magnesium, zinc or aluminium, which may be leached out, or materials which vaporize at the sintering temperature, e.g. citric acid, ammonium carbonate, or ammonium salts of organic materials, may be embedded in the coarse pored gas distributing layer 6 to form a capillary system.  The gas distributing layer 6 may be made from a coarse grained powder with either common salt or aluminium shot as the soluble filler.

Abstract: 284,533. Hogner, E. G. E. June 20, 1927. Pencil holders.- Relates to pencil holders of the kind in which the lead propeller 8 is slidable in a longitudinally-slotted sleeve 3, and engages with a screw - threaded tube 2 and a guidemember. 9 slidable within limits in the sleeve 3, the arrangement being such that within limits in the forward movement, a cam 11 on the propeller engages a slot 10 in the guide-member to disengage the propeller from the tube 2 and permit it to be drawn out longitudinally. The guide-member 9 is provided with a projection 12 extending through a slot in the sleeve 3 and is adapted when drawn out by the sleeve, to engage a stop 14 before the sleeve reaches its limit of movement. The guide is thus moved downwardly relatively to the sleeve to cause the disengagement of the lead propeller and the slot, and to bring the propeller and tube 2 into engagement again. When the sleeve is pushed back into the casing, the guide is returned to correct position by the engagement of its lower end, which projects through an aperture in the end of the sleeve, with the tapered end of the tube 2. In order to prevent the propeller 8 from engaging the slot 10 except when in the innermost position, the well of the guidemember is bent inwards slightly at 16, and, to permit the guide to yield when the propeller passes, the bottom is slotted, so dividing the projection 12 into two parts. A magazine tuba 4 is carried eccentrically by the tube 2 and is provided with a, pinion 5 engaging teeth on the inner wall of the outer casing 1, so that by rotation of the tube 2 any of the leads in the magazine can be brought into central position in the outer casing.
